, in the art to which it appertains to make and use the same.

This invention relatesto an improved method of and means for storing compressed or dissolved acetylene gas.

As is well known, acetylene gas can only be stored under pressure with safety when dissolved in a solvent such as acetone, which in its turn must be absorbed by a porous material. adapted to fill the space of the containing vessel.

This disintegration creates free-gas space V and also dust particles which are liable to blow forward with the gas and block the container valve or the nozzle of the blowpipe which is employed when using the'dissolved acetylene for oXy-acetylene welding. Silk owing to its fibrous nature does not disintegrate, but on the other hand, it is not siifliciently resilient to obviate packing when saturated with the liquid solvent and subjected to repeated vibration or bumping.

The consequence is that tree-gas space can be created after the container has once been packed to the prescribed porosity and put into use.

The object of the present invention 18 to rovide a new type of filling material which 1s superior to the above and which over- Specification of Letters Patent.

comes the inherent defects above mentioned. According to the invention the material pro posed to be employed is sometimes known as kapok, J ava'nese fiber, or Indian kapok.

One form of kapok suitable for the purpose of this invention is Erdoclend ron anf'ractuosum, but the invention covers the use of any suitable variety of kapok.

It has been found that by using this ma- .terial a much smaller quantity by weight,

than of substances previously used, is necessary to obtain a porosity of in the thus precluding altogether the possibility of free-gas space formingwvithin the con- 1 tainer after it is once packed to the required porosity. Again, the extreme lightness in weight of kapok and its comparative cheapness add considerably to the portability of the container and materially reduce the cost of its preparation.

An additional advantage of the kapok is that it has short fibers and does not form into knots or lumps. It therefore packs more closely at the start with a more homo.- geneous porosity, and the formation of pockets of free solvent, liable to blow forward with the issuing gas is thereby prevented.

I claim 1. The method of storing compressed.

acetylene gas which consists in absorbing a liquid solvent in kapok and dissolving the acetylene gas in said solvent.

2. The method of storing acetylene gas which consists in absorbing liquid solvent in kapok and dissolving the acetylene gas in said solvent.

3. The method of storing acetylene gas which consists in absorbing liquid solvent in kapok and dissolving acetylene gas in said solvent under pressure.

l. An apparatus for storing acetylene gas comprising in combination a container, kapok packed in said container, and a liquid solvent of acetylene absorbed in said kapok.

In testimony whereof I aili my signature in presence of two witnesses.
